(54) ELECTRIC MACHINE


(57) A stator core (10) is provided that can define a plurality of core slots in a surface thereof. The core slots can extend between a first and a second end portion (18) of the stator core (10). A winding (24) can be housed in the core slots. The winding (24) can define a channel (44) through at least a portion thereof. A cooling system (42) can be operably coupled with the channel (44) and can be configured to move a cooling fluid (50) through the channel (44). A turbulator (54) can be positioned within the channel (44). The turbulator (54) can be within a flowpath of the cooling fluid (50) and can be integrally formed with the winding (24).
